AUTOMOBILE FARM-WAGON.

To u/Z whom 'it muy concern Be 1t known that I, lViLLiAM LAWRENCE,

Va citizen of the United States, residing at lVashington, District of Columbia, have invented a new and useful Automobile Farm-l` 7agen, of which the following is the specification. I

My invention relates to a means of performing plowing and similar work in which is included a motor driven vehicle to which the plow or other farm implement is attached. and the object of my invention is to provide an efficient and compa 'atively inexpensive substitute for animal power in the operations referred to.

l attain the above object by means illustrated in the accompanying drawing in which t Figure l is a side elevation of my automobile plowing vehicle showing the plows in position: Fig. Q is a top view of the same: Fig. B shows the means of propelling the vehicle b v th application of a positive gearing applied to one hind wheel of the vehicle: Fig. i is a top view of the cam lever that serves to release the friction drivlng pinion vfrom the friction spur gear that actnatesl the outer hind driving wheel ofi the vehicle: Fig.` 5 is a side view of the same: Fig, is a sectional view of the fricl tion or non-positively driven hind wheel on the outer side.

Similar numerals refer to similar partsl throughout the several views.

The automobile. plowing vehicle consists of a wagon 1. a moto-r attached to a base 25. that secured to the wagon 1. A reversing clutch mechanism il. driven by a belt also secured to the base clutch Ishaft has a pulley t. that actuates a belt 9 so as to turn a gear pinion 5 which mcs-hes in a spur gear 23 secured to the driving wagon wheel T. that mainly contributesA to the traction of tht` vehicle .to which tht` plows l5 and l5 are attached as nearly as possible to the driving side. 4'.l`hc clutch mechanism 5%, being reversible. en ables the vehicle to be driven either forward or reverse without turning the wagtni. Projecting ribs are on the outer periphcries of the driving .whlels t' and 7, these grip thc Steering wheels Q0 g soil to give adhesion. operate connecting rods or chains Q1 and Q1. secured to the forward axle so as to steer in either direction and so enable the driver to easily observe the plowing. i

Specicaton of Letters Patent.

Application led April 29, 1911. Serial No. 624,119.

ratentdaan. 14, 1913.

A mechanism for enabling the Wagon to turn. to right or left consists of a friction pinion 4 on a jointed shaft 8, pivoted in a slidable pillow block 12. Thissliding is regulated by a cam and lever 11, 'operated attached to the cam lever 11. A spring 13, keeps the pinion in frictional contact with the spur QL The shaft 8 carries the posif tive pinion 5 that drives the wheel 7 by means of the spur gear 23. In plowing, the levers 19. 19, 19 enable the driver to regulate the plowing. The plow not in use is disconnected.

An essential feature of my invention is that of the positively driven hind wagon wheel that runs in the furrow made by a previous plowing, thus affording a uniform grip on the soil by the ribbed projections on the positive driving wheel. The line of pull on the plow is close to the center line of the positive driving wheel which thus minimizes strains on the vehicle and confines them to the wagon side specially con struoted to sustain them.

ln plowing around the land. I first make a furrow of uniform depth, with the wagon in forward movement using the rear plow l l5. the driving wheel runs in this furrow and guides the plow for the next one, the :sod being turned behind the wheel. In case of steep hillside plowing where the work is to and fro and not around the dand. two plows are preferable, each of which is controllable b v the driver who 'changes his scat so as to enable him to observe the plowing without ditiiculty. A pulley QQ serves to carry a drivingbelt to operate stationary machinery by the motor. Portable machinery. carried on the vehicle can also be driven thereby.

That l claim as mv invention and desire to secure by vLetters Patent is:

1. Tn an automobile farm wagon the combination of a. motor, a suitable reversing mechanism attached to t-he wagon body. means of revolving` a positively actuating hind driving wheel of the wagon to propel the latter on curved roads, a. non positively driven hind wheel co-acting with the previously named. wheel, means of Vreleasing the said non-positively driven and loosely revolnble wheel when the vehicle is being turned, asuitable steering'gear applied to l the forward axle of the wagon, loosely revolublc wheels on said axle, also operative from the fifth wheel that actuates a rod 10 means oit steeringl and otherwise controllingl the mechanism ot the vehicle and attachments by a driver on the vehicle, theA airangement of the Wagon parts being such that the center ot effort or pull is locatedas ing gear pinion that meshes in a spur gear' secured to a hind Wheel ot the vehicle, a non positively driven hind Wheel loosely i'evoluble` on its axle, a non positive spur gear secured-to said Wheel, a pinion gear' meshing' therein, a jointed shaft carrying said pinion, alsuitablenieans ot releasing,l said pinion gear trom contact with the spur gear aforesaid, a shaft connected with the jointed shaitt revolnbly mounted on the vehi ole body and joined to the positively actingl gear pinion shaft Co-aeting' with the same to propel the vehicle, a steering ,qeaiapplied to the forward axle having loosely revoliible Wheels mounted thereon, a suitable connection trom the steering gear on forward axle to steering Wheels at each ,end ot' the 1vragen controllable by the driver, a suitable connection trom the outer sliolable support ot the non positive pinion shaitt to the forward axle orA tth Wheel serving as a releasing "device 'tor the non-nositively driven Wheel when the vehicle is being turned.

8. ln an automobile Afarm Wagon having a motor, a reversingl mechanism, an opera iov tive connection from theshatt ot the reversing mechanism to the positive actin-g gear inno, ier

on its axle, a non positively driven spur gear secured to saidwvheel, a pinion gear meshing therein, a jointed shaft carrying said pinion, a siiitable means ot releasing' said pinion gear from Contact with the spur gear afore said, a shaft connected with the jointed. shaft revolubly mounted on the vehicle body and joined to the positively actingn gear pinion shalt (5o-acting with the sanieto propel the vehicle, a steering gear appliedv to the tor ward anle that has looselv revol'uble Wheels mounted thereon, a suitable connection trom the steering,r gear on the forward axle to steering- Wheels placed at each end ot the vehicle and controlled by the driver, a suitable conneetion from the outer slidable support of the non positive pinion shaftto the forward axle or fifth Wheel, serving as a releasing device for the non-positively driven Wheel when the vehicle is being turned, suitable Ilevers for use in starting,

stopping, or reversing the movement ot the placed as close as possiblel to the positively-l `driven traction wheel of the vehicle, sub

stantially as and for the specified. l

lin testimony, that l claim the foregoing as my own, l have hereto affixed my signapurpose herein ture in the presence oitwo Witnesses.
